Description

Description
The aim of this research is to develop next-generation materials for additive manufacturing (AM), especially selective laser melting (SLM). Immiscible alloys (are characterized by the presence of a miscibility gap in their phase diagrams) have gained considerable attention in the last decade due to their valuable properties and potential applications. Non-equilibrium processes like mechanical milling / alloying (MM/MA) were used to process immiscible alloys and to impact a kind of solubility in these alloys. Since SLM is also a non-equilibrium process that can process metallic materials, the focus is to develop next-generation immiscible alloys by SLM.

Responsibilities:

  • Selection of suitable immiscible systems for the SLM process
  • Parameter optimization, microstructure, and property correlation in the solidified immiscible systems
  • Careful tuning of local microstructures during the SLM processing to attain the defined combination of strength-toughness-ductility

Result
A deeper understanding of the processing of the immiscible systems and their family using SLM will be realized.

The applicants should fulfill the following requirements:

  • Masters in Metallurgy / Materials Science or equivalent
  • Experience in any / all of the following fields:
    • alloy design
    • powder metallurgy
    • additive manufacturing
    • thermodynamics
    • materials characterization
    • testing
  • Knowledge of working with CALPHAD / Thermocalc (advantageous but not desirable)
  • High level of scientific integrity, rigor, and excellence with regard to experimental methodology, analysis of data, and scientific / technical reporting
  • Ability to work autonomously while being a good team player willing to perform and develop with a team
  • Creative and innovation mindset
  • Fluency in English (working knowledge of Estonian and / or Russian may be advantageous).
